To all whom t may conc-em.'

Be it known that I, OTTO A. NEWMAN, a citizen of the United States, residing at Edwards ort, in the county of Knox and State of In iana, have invented certain new andv useful Improvements in Violin Bows, of which the followin is a specification.

This invention re ates to violin bows, more particularly to the tip and frog thereof,`and has for its object to provide, in a manner as hereinafter set forth, a violin bow formed with a tip and a frog, each having means for securely fastening the bow hair in position as well as permitting of the disconnection thereof, from the tip or frog or from both, when desired. l l

FurtherV objects of the invention' are to provide a violin bow having means for connectino and disconnecting thehair thereto,

and which is simple in its constructionand arrangement, strong, comp`act, efficient and convenient in use, readily set up in cooperative relation with respect to the staff of the l bow and inexpensive to manufacture;

`W'ith the foregoing and other objects inA view, the vinvention consists of the novel construction,` combination and arrangement of parts,` as hereinafter more specically de` scribed and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, 4but it. is to be understood that changes, variations and modifications can be resOrtedtoWhich come within the scope of the. claims hereunto appended.

staff of the bow and which is provided with a longitudinally extending bore 2"; the latter" is intersected by a vertically disposed pocket 3, which opens at the lowerV side of. the staff.

Rotatably mounted in the bore 2, is anadbar 4, which is threaded intermediate its en s as at `5. Attached to therear end of thev bar 4, as well as abutting against therear end ofthe staff, is a nut 6, which is" "i:

employed 4for conveniently rotating the bar 4.

Referring to Figures 1, 2 and 3 of the` drawings which illustrate a frog in accordance with this invention, 7 denotes the body portion of the frog, which may be formed of Vany suitable material, preferably aluminum and which has its end rovidedwith fa transverse groove 8, and with a vertically disposed pocket 9. The verted V-shape and with the walls thereof eachf'ormed withv an outwardly extending notch 10. The bottoh of the `body portion portion thereof and terminates in aj cham fered portion 14, whichis upwardly inclined. Thebody vortion 7, has a forward extenfered a's'at 16, thereby providinga shoulder 17.y Mounted on the extension 15, is ametalq lic cap 18, which conforms 'in contour to th e v contour of the extension 15, 'the latter being semi-oval in cross section. The bottom of the cap 18, is spaced fromI the vchan'nfered Portion 14, of the extension 1.5.-

The body portion 7 is positioned'against4 the lower side of the hexagonal? end -1, of the body portion andis formed with av serlesf of spaced vertically disposed sockets 19, 20,

21 and each of' which hasits wall threaded.' Carried by the bar 4, is a threaded collar'22,l having an integral peripherally threaded arm 23, depending therefrom, and 'which engages with the threaded wall of a socket for coupling thefrog to the staff. The frog pocket 9,`is of in@ i sion 15, wit the sides and top thereof chamwallsof the groove 11. vThe vertical arnr is adjusted in a longitudinal direction with respect to the staff by rotating the bar 4, thereby causing the collar 22, to shift thereon, and such action will move the frog either forwardly or rearwardly depending in what direction the bar 4, is rotated. The series of sockets provide means for adj ustably connecting the frog to be longitudinally shifted the distance desired, or in other words, the sockets enable the fro@ to be connected to the staff at dierent distances with respect to the rear terminus thereof, for example, if the arm 23, engaged in the socket 21, the frog would be positioned at a Greater distance forwardly with respect to tthe rear terminus of the staff then if the arm 23, engaged in the socket 20, or 19, and this provides for different adjustment of the frog for the purpose of tightening thel bow hairV The body portion 7, is formed with a pocket 25, which opens into the forwardA partof that portion of the groove 11, of greater depth and said pocket is adapted to receive the terminus 26, of the bow hair 24, and the latter, when connected to the frog, is arranged below the extension 15,v

extends through the portion 13 ofthe groove 11, and is then projected up into the pocket 25, as shown in Figure 1.

The bow hair 24, is detachably secured to the frog a wedge 27, a holding member and in vthat portion of the `groove 11, of.y greater depth and abuts against the up- Iturnedpterminus of the bow hair 24, and further abuts against the rear end of the holding member 28 for clamping it in position against said cap 18.

The clamping member 29 is angle-shaped and embodies a vertically disposed arm anda horizontally disposed arm. The side edges of the horizontal arm conform in shape to the side wallsofvthe lower part of the pocket- 9 and further conform in shape to the side ofthe member 29 conforms in shape to the shape of the pocket 9 and groove 8, and is formed with an opening through which eX- tends a boit 30, and with the latter having .threaded engagement with the .threaded wallsof the socket 31, which isl formed in thev rear end of the body portion 7. Then the clamping member is secured to the body portion 7, the horizontal arm is flush with the bot-tom of the body portion 7, and thev vertical arm is flush with the rear end of the body portion 7 Referring to Figures 4, 5 and (i of the drawings, which illustrate one form of bQW tip, the latter is formed with a hollow shank 32, adapted to receive the. forward end of the staff of the bow, and said shank terminates at its forward end in a depending head 33, formed at its rear with a transverse groove 34, and also provided witha pocket 35, which opens at the bottom thereof. Each of the side walls of the pocket 35, is oppositely beveled, as at 3G, and the said pocket 35, is closed by an angle rshaped clamping member 37, which is seated in the groove 34, and has its side edges conform to the contour of the side walls of the pocket. The bow hair 24, is extended up into the pocket 35, and is secured against the forward wall 38, of the pocket 35, by the clamping member 37, the latter is detachably secured in position, by a bolt 39, which extends through one of the legs of the clamping member 37 and has threaded engagement with the threaded walls of the socket 40, formed in the head 33. The bow hair 24, is extended around the bottom of the clamping member 37 and said bottom forms what may be termed bearing for the forward terminal portion of the bow hair 24. v Y

yReferring to Figures 7 8y and 9 of the drawings, which illustrate a .modified form of bow tip, the latter includes a hollow shank 41, in which is adapted to be mounted the forward end of the stall' of the bow and dependingfrom the forward terminus of the shank 41, is a head 42, provided with a `pocket 43, into which opens a socket 44, having the wall thereof threaded, The forward terminal of the bow hair 24, is secured to the head 42, by a detachable clamping member 44, which is semi-ovalin cross section, and laround which the forward terminal of the bow hair 24, is positioned. The clamping member 44,`is detachably secured to the head 42, by a bolt 45, which has threaded engagement with the walls of the socket 44. The outer face of the clamping member 44, which is flat, provides a bearing for the forward terminal portion of the bow hair 24. The clamping member 44, is mounted in the pocket 43, and the bow hair is secured between said member and the walls of the pocket 43, as shown in Figure 7 of the drawings.

`The clamping element 29, the clamping member 37, and the clamping member 44, each is countersunk for the reception of the headed endV of the bolt employed for detach'- ably securing it in position.

From the foregoing description taken in connection with the accompanying drawings, a violin tip 4and frog are set up whereby the terminals of the bow hair are securely held in position and furthermore the construction of the tip or of the frog is such that'when required, a terminal of the bow hair can bc conveniently disconnected, and although the drawings illustrate the preferred embodiment of the invention, yet it is to be understood that changes in the details of construction can be resorted to withont departing from the spirit of the invention.
